:HENRY I. WRIGLEY, OF CHICAGQ-ILLINOIS, ASSIGNOR TO UNIVERSAL DRAFT GEAR .ATTACHMENT C0., OF CHICAGO, ILLINOIS, A CORPORATION'OF ILLINOIS.

DRAFT-rna'rn FOR RAxLwAY-ARS.

To allwhom it mrg/ concern Be it known that I, HENRY I: WRIGLEY, a

l.citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful improvements in Draft-Plates'or Railway- Cars, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to plates for attachment to the draft sills of a railway'car for the purpose of receiving the ulling and buiting strains transmitted t -rough the coupler. ,y

The improved plate is especially adapted for use in connection with cars of Wood construction; and its object is to provide for adequate strength and effective thickness without massing the metal, and also to' provide an improved form of intermediate stop or limit-ing lugs whereby uniform thickness -otmetal is obtained, -the `formation of T- sections mainly avoided, andthe'necessary strength secured.

A further advantage accruing from the improved' form of stop lug is the avoidance of much of the core work heretofore found.

necessary in the manufacture of castings of this character.

' The invention is illustrated in the accompanying drawings, in which- Figure 1 is a detail plan view, partly in section, of the center and end sills 'of a car and the draft rigging mountedl thereon; Fig. 2 is a face view of one ofthe draftplates;

- Fig. 3 is a detail in perspective of a portion of' the draft plate showing one of the jstop lugs* with some parts broken away;

and Fig. 4 is 'a detail-ia" perspective of tllie same portion of theplate viewed from the Teal'.

It is the usual practice, in the manufacture offcars of wood,'to secure the draft plates to the inner faces of a pair of draf-t timbers mounted immediately below the center sills. For added strength the draft plates are usually provided with upstanding horns Whichbear against the inner faces of and are bolted to the center sills,`the forward horn abutting against the rearward face of the end sill of the car. In the drawings a draft plate of this form is shown.

vOne of the center sills of acar is represented at 10, and at 11 there is shown one of rthe draft-sills, the center sill with which Speccaftionzof Letters Patent. Application filed `August 16, 1913. Serial N o. 785,055.

it is associated being omitted. The end Sill is represented at 12. The coupler shank is shown at 13 and the yoke at 14. A pair of tandem springs is shown at 15, 16, the forward spring 15 being located between a pair of followers 17, 18, and the rearward spring y 16 between a pair ot' followers 19, 20.

The body of the draft plate is represented at .21. It is of uniform thickness but'is composed o a plurality of longitudinally disposed sections, as 22, 23, alternate sections eing offset backwardly and forwardly, respectively, with reference to the median vertical plane of the plate, thereby increasing the eEec't-ive 'thickness of the plate -without increasingits weight or requiring the massing of metal to produce ribs for giving the plate the required thickness.

The several offset. port-ions of the plate are of substantial width and present fiat faee's,those, as 22, which are backwardly offset give the required area of bearing surtaceI u on the sills,' and those, as 23, which are o set forwardly form the bearing surfaces for the edges ot' the follower plates and are sutiiciently wide to avoid excessive wear. The plate being cast. as an integral piece, the described form avoids any massing of metal, there being a uniform actual thickness ol metal throughout, while giving a maximum thickness of the plate as measured from the inner or front face oi the instanding sections 23 to the rearward iace ot the backwardly offset sections 22, which is required car practice, the follower plates being of standard size.

The intermediate stop or limiting lugs which determine the range ot' movement of the followers and thus, prevent undue compression of the springs are cast 'integral with the plate, and their form is best shown in Fig. Each of these stops may be described as comprising a pair ot' oblong rectangular sections 24, 25, each formed of vinstanding walls of uniform thickness with `the body of the plate, the two sections being for securing the plate to the sill.l In casting this toi-1n the only core'requiredis that which provides for the space-intermediate of the two sections 24,25, and coveredv by the web 2.6. While the walls of the stop thus of their ends, as shown 4at 29, by an apertured bridge through which the securing bolt. is passed. 'The ribs 28v are located immediately back of the intermediate Stops, -so that the bolt-hole through the bridge 29 is in line with the bolt-receiying aperture 27.

So much of the invention as appertains to the intermediate stops is not, however, claimed in this application, as it is made the subject of an application which is a division of this one.

The necessary draft shoulders 30, 31, 32 and 33 are formed upon the plate, the intermedi ate shoulders 3l, 32, being formed by looping the body of the plate inward, and the end shoulders and 33 being reinforced porting walls of the several draft shoulders for the attaelm'ient of tie straps uniting the two draft plates ol the car and supporting the draft rigging. for engagement with the center and end sills are shown at 40 and 41. y

I claim as my inventionposed of av plurality of longitudinally, -e1:- tending integral sections havingjf'atl'aurfaces, adjacent longitudinally parallei'sec- -tions being offset, respectively, inwardly and outwardly.
